Q: What are the benefits of sweet clover?
A: Sweet clover is used to increase the loss of water from the body through the urine (as a diuretic). It is also used for varicose veins and to relieve symptoms of poor blood circulation (chronic venous insufficiency) including leg pain and heaviness, night cramps, itchiness, and fluid retention (edema).

A: Poisoning Concerns Sweet clover contains a substance called coumarin, which is converted to dicoumarol by mold in hay. Dicoumarol is an anti-clotting agent that will cause livestock to hemorrhage (bleed). This can be internal bleeding so there are no apparent signs of the problem looking at the cattle.

Q: Is sweet clover good for the soil?
A: Sweet clover is renown for improving marginal soil by increasing the organic matter quickly. Plants are tolerant of heat and shading. Tap root is fairly aggressive and is able to loosen hard soils. Yellow blossom has very good winter hardiness.

Q: Is sweet clover a good cover crop?
A: Once established, sweetclover is the most drought tolerant of all cover crops that produce as much biomass. It is especially resilient in its second year, when it could do well in a dry spring during which it would be difficult to establish annual cover crops.
Source

Q: Will yellow sweet clover reseed itself?
A: Yellow Sweet Clover spreads by reseeding itself, and it often forms colonies at favorable sites. The sweet hay-like aroma of the foliage is caused by coumarin. Cultivation: The preference is full or partial sun, moist to slightly dry conditions, and a somewhat heavy clay-loam soil.

Q: Does sweet clover come back every year?
A: Sweet clover can be an annual or a biennial depending on where it is planted as well as the cultivar used. Sweet clovers are an excellent soil-builder because they have a deep taproot that extends through the soil profile which takes up nutrients and minerals that can be used by crops.
Source

Q: What month do you plant clover?
A: Plant clover in the spring or early summer, when the ground has become soft and moist from the spring rains. You may also plant in September or early October in most locations. Clover seed is very small, so you may want to mix it with lime or fertilizer to give you more substance to work with.
Source

Q: What month do you spray clover?
A: The best time to spray is in the early spring. Spray the weeds to wet but not to the point of runoff. Repeated application may be necessary about 6 weeks later to treat clover since it is a persistent weed.
